IMPROVEMENT IN DIVIDBRS.

TO ALL WHOM IT MAY CONCERN: 1 Y' I' Be it known that I, O. E.WEATHERHEAD, of Winchendon, Worcester county, Commonwealth ofMassachusetts', have invented certain new and useful Improvements inDividers and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon. In the drawings- Figure1 represents a' pair of dividers with my improvement.

Figures 2 and 3 being detailed viewsof parts'of the same. i

This invention consists in a pair of dividers, more particularly ofthekind used by carpenters andjoiners, in which one of the legs is arrangedso that an ordinary lead-pencilv may be inserted and adjusted for use,with readiness, my improvement being comprehended in the construction ofthe leg for this purpose.

In construction, I form the dividers of one leg, A, formed as usual, andthet other leg, B, as follows: At a suitable distance from the hinge theleg B is formed, with an elbow, C, projecting 'at or near 'a right anglefrom the leg B outwards. This elbow, C, is' made suiciently'wide toadmit of a hole being made through it at a, for the pencil D to comethrough. From the outer end oi' this elbow again extends downwardsapiece, E, having` a clamp, F, upon it, which is arranged with aset-screw, b, so that the clamp may tighten the pencil against the pieceE, and hold it firmly in place whenever adjusted. The piece E is formedwitha groove, c, along its whole length on the inner` side, which,conforming in shape to the surface ofthe pencil, allows the latter totit snugly against it. An end view of the clamp F is shownl in fig. 3,where it is seen that it consists of a collar, fitting squarely upon thepiece E, and continuing the circleof the groove in the piece E, so thatit closes closely up on the pencil when clamped. This clamp can be movedup or down the piece E at pleasure, and tightened by the set-screw Zz.In g. 2 is shown an iron or steel point, G, in -place of the pencil. Apen for ruling may also be changed in place of either pencil or plainpoint, if convenient, or to suit occasions. l

The advantages of my improvement are in the increased facility by whichan ordinary lead-pencil may be I adapted to the dividers, and in thesecure method of holding the same in place, and adjusting it atpleasure.

Having described my invention, what I claim as new, and desire tosecureby Letters Pa.tent,'is- The device for holding a pencil point, orpen, upon the dividers, consisting of the elbow C, piece E, with groovec, and clamp F, with set-screw b, arranged and combined substantially asdescribed.
